After changing the axis maximum here I want to have the step size change so I can see a label for 130.  How can I accomplish this? 

I have placed a text box control and I have to write validation rule for it.

But the problem is I have bound a collection to the grid view and I have declared only two columns 

one for binding Name

other for value [data template changes depending on property] so I have  overridden selecttemplate method . Based on the item input I have choosen the datatemplate.

Now if write a validation rule for text box ,it applies for all the text boxes in grid.The rule should be individual for each textbox

Can you help me resolving the issue.

Hello,

I'm trying to connect a connector with the shape created dynamically when a connector is created from a existing shape but the user drop the connection on an empty space.

Actually i m able to create the new shape at the right position (on the EndPoint of the connection) but i m possible in the AddLink method to associated the connection with the new shape on the right connector .

The connection is never associated with the connector when i set the TargetConnectorSource

As stated in http://docs.telerik.com/devtools/wpf/controls/radrichtextbox/getting-started/getting-started I added the below references to my WPF project and a simple XAML declaration of RadRichTextBox and the project builds fine and RadRichTextBox is visible in Visual Tree while debugging but it is not rendered on the screen using both VS 2015 and VS 2017. If I replace it with standard WPF RichTexBox everything works fine. I am unable to find anything on this problem in forums or in documentation so what is the problem here and how to resolve it?

Sample project attached (It's a zip file but it's not allowed so I changed the extension to jpg).

Telerik.Windows.Controls
Telerik.Windows.Data
Telerik.Windows.Documents
Telerik.Windows.Documents.Core
Telerik.Windows.Documents.Flow
System.ComponentModel.Composition

     I am programatically setting the RangeEnd and RangeStart of the scroll bar and moving it dynamically as data comes in. This works fine until you manually move the scroll bar. There is a case where the data is reset and I set RangeStart back to 0 and RangeEnd to a number greater that that (0.25 for example) but the scroll bar stays where it was if the user has touched it. If the user has not touched it the scroll bar resets just fine. I am curious if in the logic there is a setting that prevents setting RangeEnd and RangeStart once the scroll bar has been scrolled manually? If so is there a way to reset it outside of recycling the object?

Hi,

in my radSpreadsheet I do this actions:

- insert an empty row (insertEmptyRow.jpg)

- than copy the hole row (copyRow.jpg)

- than paste it in the first cell of the before inserted row (pasteRow.jpg)

- and than I insert an empty row again --> An Error comes up (errorColumnIndex.jpg)

From this point on my Worksheet has this 16383 columns and I can not get rid of it.

What I tried so far wars:

ControlCenter2.radSpreadsheet.Workbook.ActiveWorksheet.Columns.Remove(200, columns.Count-200);

but this had no effect, all the columns are still visible and scrollable.

When I try to delete this columns in GUI the next error occures: (delCol.jpg, errorNullRef.jpg)

Sorry for the german in pics.

Can you help?

Hey guys,

I like the way the ColumnsSelectionButton looks on the right side of the group panel.  Instead of using it for selection, would there be a way to easily reuse this control to show/hide the associated column?

Thanks!
